IMPROVEMENT l IN staunt/membres.

` '.'ll'heV Schedule referred toin these Letters Patent and makin part of the same.

To all whom 'it may concern.-

Be it known that I, FRED IHnnNnn'LDT, of the town of Le Roy, county'of McLean and State of Illinois, haxfeinverr'tedva new and usefulImprovement in Saint-Machines; and I do hereby declare that the following is a clear, full, and,l exact description of the construction and operation of the same, reference being `had to the accompanying drawings and letters of reference marked thereon, in which drawings;

i Figure l is ai verl-ical sect-ion through the center of machine, taken at the line a: x, iig. 2.

Figure 2 is a top view of the same. p y The nature Vof my invention relates to an improved arrangement of pa1=ts,and which parts consist princi- Vpally'ot adru'm or external case, of a conical shape,

with an interior revolving cylinder of like shape, but.

and operating-Shadi.

i ,lo enable others skilledin the artto' make and ofsmaller diameter, a sitter, t'an,"1,rnlley, eccentric cam,

` use said invention, I will proceed to describe the va. vrions parts in detail of which it is composed, aud my improved arrangement of the same for operation, as hereinafter described.

A.irr the drawings representsV the outer case or drum, barred inwardly; B, the revolving cylinder, burred` outwardly.

G, vertical spindle or shaft, terminating in bearings in the framework H,

E, fan-case.

D, fansa,n p

G, bandpulley, attached to the shaft, operated vin the usual manner' by horse or other power, communieating revolving rnotionto the inner cylinder B.

J, eccentric uponsad shaft G, connecting withvand imparting a compound'rvibratory motion tothe sifter lL-aperture in the bottom of theV drum, directly above the sifter, througlrwhich.` the. graia passes, where, bythe fau-,blower D, it is cleansed of cha and l other impurities, `the grain Vnow passing through the perforations of the sifter K, andentering through the funnel or tube L into a receptacle below.

The operation isl as-follows:

V Thegrain to be scoured is passed into the opening Mon the topof the drum, passing down through the circular .inclined burred chamber, formed betweent-lre ldrum and revolving cylinder', where it comes into repeated contact, .inits passage downward, withrthe burs of each necessarily/'and eiiectuall scourimr it a portion of the lighter rmpurrtres,sucl1 as dust, 85e.,

being driven by the upward current of air out through Y the opening F on thel top ofthe drum, and the rernainder being thoroughly sift-ed and separated from the grain, and thrown ott from thesifter K by means of'fa-n D, and the compound reciprocal and vibratory motion ot' said sifter'irnpart-edto it through. the mediurn of cam-J' on shaft `G. .-7 L

Having thus fully described my invention,

I wish it t-o be distinctly understood that I do notclaim as new the several devicesI above described, nor

any general combination of the same; but

That I do claim as new, and desire 'to secure by,v

Letters Pat-ent, is-

. The improved arrangement, in relationvto the stavtrionary drum A, 'revolving cylinder B, shaft C, fanblower D, and pulley G, of the cam J yand sifter K, operating in the manner and for the purpose set forth and described. l
